General number field sieve

The General Number Field Sieve (which is informally 2/3 of the way towards being polynomial in the number of digits (but is still exponential)) is the best known way to factor large integers, in that it scales the best for very large numbers. We're talking like 150 or more digits. And stop reading urban-dictionary and go ask google or something you nerd (just like me ;3) see also: "Special Number Field Sieve" (not on here!)

For numbers with 150+ digits, if you're not going to use the GNFS (General number field sieve), then tbh just don't bother.

Elliptic curve

(NOT AN ELLIPSE!!!) Elliptic curve: y*y = x*x*x + A*x + B for some A and B. Seemingly simple enough (if you've gotten past high school algebra at least). However, if you make some special points, you can create a whole new number system. And there are so many of these (just change your values for A and B).

Elliptic curve cryptography are based on the idea that multiplying by, say, 329857349875 isn't *that* hard... but dividing by it is HELL. It's a reliable one-way function, which is pretty important for encryption! Another application is factorization, but I'm not too sure on that one so ask google ig

Make minecarts faster

"Make minecarts faster" is a catchphrase commonly said in camman18 shorts. It references the fact that minecarts take so much effort to set up but are basically useless as they are slower than even SPRINTING.

Literally every short by camman18: "Also make minecarts faster"

ax^2 + bx + c

Quadratic equation with quadratic coefficient a, linear coefficient b, and constant coefficient c. Common way to represent a quadratic (as well as sometimes with the square completed, or with a quadratic coefficient and roots)

ax^2 + bx + c <=> 2ax = b + sqrt(discriminant) or b - sqrt(discriminant), where the discriminant equals b*b - 4*a*c

Group theory

Field of abstract algebra dealing with how different symmetries relate to each other (e.g. are they equal? parts of each other? "multiply" to give some other group we want?)

There's a nice VISUAL introduction to group theory which is (imo) watchable at mid-high school levels (15+ yo ish): 3Blue1Brown's video currently titled "Group theory, abstraction, and the 196883-dimensional monster"

Compact Claustrophobia

Compact Claustrophobia is a Minecraft FTB (Feed The Beast - not the being angry one, but the custom challenge map making heavy use of mods) modpack. Its premise is based upon being stuck in a small bedrock hallway and entering a 3 by 3 by 3 room. In this room, you craft materials to create larger rooms (5x5x5, 7x7x7, 9x9x9, 11x11x11, 13x13x13) and automate many tasks in a heavily modded playthrough. The player (in an ideal playthrough) eventually gets access to a bedrock pickaxe to break the bedrock chamber they spawn in, and continue to progress in the Overworld (if they wish to) and beat the Ender Dragon by use of an "End Cake" that teleports you to the End.

Compact Claustrophobia is a Minecraft modpack based on the Compact Machines mod that allows you to fit rooms inside a single block.
"I escaped Compact Claustrophobia and all I got was this lousy T-shirt"
I finally got a Nuclear Furnace in early-game Compact Claustrophobia and it is like 70 times faster than a regular furnace lol
If you don't go the way of automation in Compact Claustrophobia, you will go through a long and hard slog of manually grinding (or macroing if you're into that for some reason).
Compact Claustrohpobia without Click Machine is like doing pushups on your knees, it just doesn't work out

Strawberry Jam

1. Strawberry jam is a sweet preserve made from strawberries and sugar. It's typically spread on bread or toast.

1. you should try eating strawberry jam its so good ngl

2. well if you're looking for a popular Celeste mod you can't go wrong with SJ
